Prayer of St. Thomas Aquinas before Mass

Almighty and ever-living God, we approach the sacrament of Your only-begotten Son Our Lord Jesus Christ. We come to the doctor of life unclean to the fountain of mercy, blind to the radiance of eternal light, and poor and needy to the Lord of heaven and earth.

Lord, in your great generosity, heal our sicknesses,
wash away our defilements, enlighten our blindness, enrich our poverty, and clothe our nakedness.

May we receive the bread of angels,
the King of kings and Lord of lords,
with humble reverence, with the purity and faith,
the repentance and love, and the determined purpose
that will help to bring us to salvation.
May we receive the sacrament of the Lord’s Body and Blood, and its reality and power.

Loving Father, as on our earthly pilgrimage
we now receive Your beloved Son in the holy sacrifice of this Mass, may we one day see him face to face in glory, who lives and reigns with You for ever. Amen.
